Large seatpost bagI had issues with this product in that the plastic seatpost bracket snapped after only a few uses - wiggle replaced without issue but in the end I decided to replace with a Blackburn seatpost pack which was slightly more expensive but much more suited to my requirements.

Altura Arran Expanding Post PackGreat little bag very versatile holds everything I need for a day out, tools jacket specs gloves mobile phone and some food, clips on and of very easy only wish that they would sell you another post clamp so that you could change it to other bike

Is there a way to fit a rear light to the bag or its fitting?

Asked by: AndyHenderson

The reflective strip on the back of this pack has an un-sewn slot in the center rear about an inch above the bottom that allows you to clip on a rear light. However, most rear lights will hang below the bottom of the pack. I plan to sew a piece of webbing to the snap flap that attaches the bag to the wire rack to make a slot higher up that won't risk breaking my light when I set the bag down with the light attached.

Weight and dimensions

Please can you tell me the weight and dimensions of the Arran Expanding Post Pack? Thanks,

Asked by: pottermiss

I weighed mine at 550g (including my back light which is attached to the frame!). It's very light when empty!
Dimensions: It tapers from approx 10-17 cms wide, is 15-19 cms deep, depending on whether it's expanded or not, and is 27 cms long.

Is it suitable for a carbon fibre 31mm seat post?

Asked by: tobyker

We can't recommend that you use clamps on a carbon seatpost in case the carbon is pinched or folds.

How much room is needed on the seat post for the bracket?

I have about 2&quot; spare on my post - will that be enough?

Asked by: Eldon

I can confirm that the clamp will not need more than 2&quot; of post to be fitted to. I hope this helps.

How long does the seat post need to be?

When expanded this bag looks like it needs to be fitted at the bottom of quite a long seat post if it is to fit under the saddle. What length of seat post is needed to ensure that it will fit when expanded?

Asked by: Eldon

I have 5 &quot; of post and its fine

Is the bag waterproof?

Looking at doing some light touring in a few months. I'm concerned about changeable conditions, and my gear getting soaked.
Just wondering if the material on this bag is waterproof/ water resistant?

Asked by: Poxon

I can confirm that this bag is not waterproof so you would need to get a waterproof cover for the bag. Unfortunately we do not stock anything suitable. I hope this helps.

Altura Arran seat post bagAre spare clips available

Altura Arran Expanding Seat Post Bag.
Is it possible to buy spare clips-the one that fits round the seat post plus the moulded plastic clip-for this bag, so that the bag can be quickly swapped between bikes, without buying a second bag?

Asked by: tandemike

They can be bought, but Wiggle don't stock them.
Just google &quot;Altura Seat Pillar Adaptor For Post Pack &quot; and you should find exactly what you're looking for.
